The first time I tried making a panorama was a bit of a stretch since at the time (1967) I had no idea how I was going to blend two images together to make the panorama. This is Mooney Falls in Supai Canyon taken with a twin lens reflex camera on Ectachrome film:

A number of decades later I got a Tilt-Shift lens (Canon 24mm TS-E) while shooting a Canon 5D MkII and used the shift feature to create panoramas without the usual distortion issues. This is a 3 shot panorama from a nice morning at Reflection Lakes below Mt. Rainier:

The TS-E lens was also good for getting a wide depth of field with the tilt function. This was very useful prior to using focus stacks to get the same result. A shot from a moonlit session at Badwater in Death Valley:

Finally an example of using a focus stack for extreme depth in a small scene - in this case False Lily of the Valley at Cape Blanco State Park along the Oregon coast:
